Biopel MINI - Installation and Operation Instructions
42
Set the boiler response type to the instruction from the thermostat. The thermostat can turn the boilers off/on
immediately, or it can lower the set CH temperature if the thermostat detects the room temperature has warmed to
the set value:
o
Immediate switching off/on of the boiler by the thermostat:
Activate the Ignition function in the Installation Menu, Room Thermostat.
If you want to switch off the CH pump together with the boiler, activate the CH pump - room thermostat
function in the Installation Menu, Room Thermostat. Beware of possible overheating the boiler if the
pump is switched off together with the boiler!
o
Lowering the CH set temperature using the thermostat:
Deactivate the Ignition function in the Installation Menu, Room Thermostat.
Set the lowering level of the CH set temperature in case the thermostat does not give a heating
instruction in the Temperature lowering by thermostat function in the Installation Menu, Room
Thermostat.
The value by which the set CH temperature has just been lowered (in case the room thermostat is not
currently giving a heating instruction) will be displayed on the Main Panel, under CH Set Temperature.
This regulation method is particularly advantageous for heating systems with large quantities of water,
where lowering the CH set temperature will ensure that the system is heated to the required level more
quickly without the system cooling down. Otherwise, it would take a long time for the cooled water in
the system to heat up again.
The boiler will heat the DHW even if there is no requirement for central heating from the room thermostat.
11.2.
Two CH c DHW
Connection with two central and floor heating circuits (controlled by mixing valve 1, 2 and valve pump 1, 2) and
a domestic hot water circuit (controlled by DHW pump):
Protection of the boiler against low temperature corrosion by a thermostatic valve (50°C and above).
Boiler regulation according to CH set temperature (60°C and above) and DHW set temperature and floor heating
(according to customer requirement).
All control elements and accessories are connected to the control unit located at the front of the boiler.
Connection of pumps:
o
Connect the CH pump to the control unit at the CH pump output.
o
Connect the DHW pump to the control unit at the DHW pump output.
o
Connect the Valve1 pump (OT) to the control unit at the output of the Valve1 pump (OT pump, radiators).
o
Connect the Valve2 pump (PDL) to the control unit at the output of the Valve2 pump (PDL pump, floor heating).
